Computation of the von Neumann entropy of large matrices via trace estimators and rational Krylov methods
Michele Benzi, Michele Rinelli, Igor Simunec
We consider the problem of approximating the von Neumann entropy of a large, sparse, symmetric positive semidefinite matrix , defined as where $f(x)=-x…
Structural analysis of water networks
Michele Benzi, Isabella Daidone, Chiara Faccio +1
Liquid water, besides being fundamental for life on Earth, has long fascinated scientists due to several anomalies. Different hypotheses have been put forward to explain these pecu…
Efficient preconditioners for solving dynamical optimal transport via interior point methods
Enrico Facca, Gabriele Todeschi, Andrea Natale +1
In this paper we address the numerical solution of the quadratic optimal transport problem in its dynamical form, the so-called Benamou-Brenier formulation. When solved using inter…
Solving linear systems of the form by preconditioned iterative methods
Michele Benzi, Chiara Faccio
We consider the iterative solution of large linear systems of equations in which the coefficient matrix is the sum of two terms, a sparse matrix and a possibly dense, rank defi…
